Answer:

C) 3/5

Step-by-step explanation:

Have you heard of this way to memorize the trig ratios?

SOH-CAH-TOA (Say it out loud so you remember it.)

It represents these ratios:

Sine = opposite side / hypotenuse

Cosine = adjacent side / hypotenuse

Tangent = opposite side / adjacent side

In this problem, cos C = adj / hyp = BC / AC = 24 / 40.

That simplifies to 3/5

Find the equation of the line perpendicular to y = -2x + 6 that goes through (2, 10).

neonofarm [45]

If the line is perpendicular, then its slope is the reciprocal of the given line's slope. This new line's slope is 1/2. We plug it into slope-intercept form

y = 1/2x + b

Now plug in the given point of (2, 10) and solve for b.

10 = 1/2(2) + b
10 = 1 + b
9 = b

So your equation is y = 1/2x + 9

Use the multiplication property of exponents to determine if each statement is true or false.

lisabon 2012 [21]

1)
LHS:
${a}^{4} \times {a}^{3} \times a \\ = {a}^{4 + 3 + 1} \\ = {a}^{7}$
LHS = RHS. So, the statement is true

2)
LHS:
${5}^{2} \times {3}^{4} \\ = 25 \times 81 \\ = {5}^{2} \times {9}^{2} \\ = {45}^{2}$
LHS not equal to RHS. So, the statement is false

3)
LHS:
${x}^{6} \times {x}^{0} \times {x}^{2} \times {x}^{3} \\ = {x}^{6 + 0 + 2 + 3} \\ = {x}^{11}$
LHS = RHS. So, the statement is true.

4)
LHS:
$7 {m}^{2} \times 2m \times 4 {m}^{5} \\ = (7 \times 2 \times 4) {m}^{2 + 1 + 5} \\ = 56 {m}^{8}$
LHS = RHS. So, the statement is true.

Which choice is equivalent to the product below?<br> Square root 2 • square root 3 • square root 8

SIZIF [17.4K]

That would be simplified into

1.41 • 1.73 • 2.82 = 6.9

i don’t know what the choices are bc you didn’t put them but hopefully this does someone some good <3

I need to know how to find the mean for 77,82,87,85,32,78?

lys-0071 [83]

Answer:

73.5

Step-by-step explanation:

To find the mean, sum the data and divide by the amount of data

mean = $\frac{77+82+87+85+32+78}{6}$
